Which best explains how convection currents are affected by the temperature of coastal areas?

• Coastal areas are cooler during the day and warmer during the night.

• Coastal areas are warmer during the day and cooler during the night.

• Coastal areas have no changes in temperature between the day and the night.

Which of these events have the MOST influence on regional climate?

• frequent tornadoes

• ocean trade winds

• hurricane

• thunderstorm

• tornado

Which of these is associated with hurricanes?

• a storm that forces strong winds toward the ground
